Solar cells are an excellent option where it is difficult to connect to the general power grid, for instance in summerhouses or mountain huts. They can also be used to produce electricity for private use and it is then possible to use 12 voltage lights along with the traditional 220 voltage system. Some people, for instance only want to have a 12 voltage light in the bedroom in order to avoid the possible impact of 220 voltage electricity.
However, considering how moderate the energy prices are here in Iceland, and then how expensive the solar cell equipment still is, solar energy cannot be said to be directly competitive on the market. Solar energy can nevertheless be a welcome addition and come in handy in certain places.
The northerly location of Iceland also has an effect on the lighting conditions. There is not enough light during wintertime here in order to make the solar cell a feasible option for electricity production. It needs many cells to take advantage of the sparse light, and they are expensive. But it is expected that soon, solar cells will be on the market that are cheaper in production and more comfortable to use.
